Maybe I'm missing something but I've been with Tricare prime for the last 6 years as my only health insurance. I have dental and vision through FDX. Maybe its my location in CHS, but I've never had any issues with it. There are lots of specialists and doctors here that take Tricare. I covers my wife and I here in CHS area and my kids well while they're away at college. I've had a few procedures done on Prime and it's never been a problem. Using E-scripts for my wife are cheap and the minimal copay a the local grocery store pharmacy is reasonable. What am I missing out on. obviously too late to change the FDX now for 2020.
